Specification of Letters Patent.

Application filed October 7, 1914. Serial No. 865,488.

To all whom it may concern Be it known that we, GEORGE KoMARosE- virsand Garcon TRAIBER, subjects of the King of. Hungary, residing atLorain, in the county of Lorain and State of Ohio, have invented certainnew and useful Improvements in Safety )evices for Locks, of which thefollowing is a specification.

T his invention relates to certain new and useful improvements in safetydevices for looks.

lhe primary object of this invention is to provide a safety meansadapted to be readily positioned within the key-hole slot of a lock andremovably retained therein and preventing the entrance of the key forthe manipulation of the lock structure.

A further object of the device is the provision of a two part safetymeans, one being employable for positioning the other within the keyholeof a lock and for displacing portions thereof to prevent its removalexcept by aid of the positioning means.

A still further object is to prevent the employment of anylock-actuating means by positioning a key-hole slot obstruction therein,the same being removably positioned and removed at will by aid of apositioning means.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists thenovel combination and arrangement of parts to be hereinafter more fullydescribed, illustrated in the accompanying drawings and set forth in theappended claims.

in the drawings formin a part of this application and in whichlike-designating characters refer to corresponding parts throughout theseveral views, Figure 1 is a vertical longitudinal sectional viewthrough a portion of a door and casing, a portion of one side of thedoor lock being broken away and the obstruction means illustratedpositioned therein. Fig. 2 is a front edge view of the door partiallyshown in vertical transverse section upon the plane. of the key-holeslot of the lock, the obstruction means being shown in position. Fig. 3is a horizontal sectional view through the key-hole slot of the door andlock with the obstruction means positioned therein and the positioningmeans in engagement there with. Fig. 1 is a view similar to Fig. 3 butwith the obstruction means arranged for ready removal. Fig. 5 is anenlarged side elevation of the obstruction means partially broken away.Fig. 6 is a front elevation of the obstructing means. Fig. 7 is a transverse sectional view taken upon line V 11-4111 013- Fig. 5, and Fig. 8is a transverse sectional view taken upon lines VlIlVII1 of Fig. 5.

Referring more in detail to the drawings, the door 10 is illustratedwith a lock casing 11 secured therein, the said casing having oppositelypositioned key-hole slots 12 in alinement with the opposite key-holeslots of the door, all of which constitutes the usual arrangement ofsuch elements.

lV hen the door is locked, it is desirable to prevent the entrance of akey or other lock manipulating means by any other than an authorizedperson and such a result is now efiiected by employing an obstructionmeans or element let which is readily positioned within and removed fromthe keyhole slot by means of a positioning means or element 15.

The obstruction means consists of a substantially key-shaped memberhaving a cylindrical shank 16 and a lateral ward 17 projecting from oneend thereof. A side plate 18 is journaled upon the shank by means of thesleeve 19, which sleeve is interrupted at its middle portion as at 20allowing for the accommodation of a finger 21 carried by the plate 18which engages the hexagonal portion 22 of said shank and forms a ratchetmeans for the turning of the plate upon the shank. A pin 22 prevents aremoval of the plate 18.

The shank is provided with a reduced cylindrical end portion 23 at theend opposite to the ward 17 while the plate 18 is provided with aprojecting hook 241 lying adjacent the reduced portion 23. A positionmgmeans 15 comprises a shank 25 having a central bore 26 at one endthereof adapted to be received for free revolution upon the reduced endportion 23 of the shank 16, while the said end of the shank 25 isreduced as at 27 for reception within the free end of the sleeve 19. A.side ward 28 having a perand positioning means 15 are employable Withany manner of lock which provides an unobstructed key-hole slotextending from one side of the door to the other. By positioning themeans 15 upon the obstruction means as illustrated in Fig. 4, the twomembers may be readily inserted into the lock as shown in said figure,and whereupon the ward 17 will be placed within the opposite slot fromthat through which it was inserted and as illustrated in Fig. 3, aturning of the member 15 a partial rotation will position the plate 18at an angle to the ward 17 thereby placing the obstruction means in sucha manner as to prevent its ready removal from the lock. The shank 25 isthen rotated in a reverse direction upon the reduced end 23 thusreleasing the hook :24: and allowing the positioning means to be removedfrom the key-hole slot by bringing the Ward 29 in alinement with theslot. When desired to remove the obstruction means from the lock, themeans 25 is reinserted and turned for re'e'ngagement with the hook 24and whereupon a continued revolving of the shank 25 brings the plate 18into alinement with the ward 17 so that the obstruction device may bereadily removed from the lockthrough either one of the keyhole slots.

The plate 18 is slightly retained at any angle with respect to the ward17 by means of the resilient engagement of the finger 21 with one of thefaces of the shank portion 22., It will be evident that with the member14: positioned within the lock, the usual key orany other instrument cannot be inserted through either key-hole for successfully manipulatingthe lock mechanism, while the obstruction means may be readily removedby the member 15.

While the forms of the invention herein shown and described are what arebelieved to be the preferred embodiments thereof, it is nevertheless tobe understood that minor Copies of this patent may be obtained forchanges may be made without departing from the spirit and scope of theinvention as set forth in the claims.

What we claim as new is 1. A lock device comprising in combination witha lock having opposite key-hole slots therethrough, an obstructionmember comprising a shank having a reduced cylindrical end and anintermediate hexagonal portion, a lateral ward upon said shank at theend thereof opposite to the cylindrical end thereof, a plate at the sideof said shank and revolubly journaled thereon and having a cut-awayportion adjacent the hexagonal portion of the shank and a resilientfinger carried by said plate engaging the said hexagonal portion.

2. A look guard comprising an obstruction means consisting oi a shankhaving a reduced portion at one end, lateral ward rigidly secured to theother end of said shank, a plate journaled upon said shank and having amiddle cut-away portion, a pin' carried by said shank and engagingwithin the cut-away portion of said plate, flattened surfaces upon saidshank, a resilient finger carried by said plate and engaging the saidsurfaces, an end hook provided upon said plate, a positioning memherhaving a shank provided with an end bore adapted for turning upon thesaid reduced portion of the obstruction means shank, and a perforatedside ward carried by said positioning means engageable with the saidhook during the turning movement of the plate.

In testimony whereof we aiiix our signatures in presence of witnesses.
